Specific implementation mode
Embodiment
As shown in Figures 1 to 5, the end tooth cutting tool of a kind of cutting edge of the invention on the circular arc of circumference, including one
Round bar shape cemented carbide body 1；One end of the round bar shape cemented carbide body 1 be equipped with cutting edge 2, the round bar shape cemented carbide body it is another
One end is set as handle of a knife 3；The cutting edge 2 is by one section of circular arc on the circumference for one end end for being located at round bar shape cemented carbide body
End tooth shape cutting edge 21 constitute；The cutting edge is in the projection from one end end of round bar shape cemented carbide body to shank direction
Constitute crescent 22.
In the present embodiment, the end tooth shape cutting edge 21 of one section of circular arc be it is multiple, certainly, one section of circular arc
End tooth shape cutting edge may be one.
In the present embodiment, the top line of the multiple end tooth shape cutting edge 21 constitutes contour.It is of course also possible to be another
The top line of a kind of scheme, i.e., the multiple end tooth shape cutting edge constitutes the curves such as curve, such as parabola.
From the crescent position of end, section extends equipped with chip space 4 inwards for one end of the round bar shape cemented carbide body 1, should
